fun fact for Paraguay: the Itaipu Dam is one of the largest in the world located between Brazil and Paraguay, where each country gets 50% of the production. But 50% of that production for Paraguay, a country of 7 millions inhabitants, means that it cannot consume that much, so it's essentially reselling that energy to Brazil, a country with 30x more inhabitants. Paraguay only uses about 1/3 of its share (and thus resells 2/3 to Brazil).

And it means that it has been oil free since the 70's.

Brazil, a continental country, has more than 80% of its energy from renewables

  • Oil free for electricity generation. The media in my country (Finland) also likes to brag about 90+% fossil-free electricity generation. But electricity is under half (30%?40%?) and the rest of that energy isn't fossil-free.

    • Finland has electricified 40% of primary energy which is pretty much world leading (Sweden and Norway are 50%). European average is 19%.

      Largest chunk left is transport which can mostly be electrified now. Industrial and home heat too. There are hard to electrify sections in both but overall it's fairly obvious what to do next.

      And the easy parts eliminate 3 or 4 units of primary energy for every one they replace, so even 40% primary energy is way over 50% toward the finish line of electrifying all the useful stuff.

      I think it's also an interesting question as to whether countries that use a lot of electricity have lower per kWh prices because they spread the fixed costs further.

      The trick of course is that if you electrify heating and transportation they'll need much less energy. Your average car with an ICE has an efficiency of 20-40%, electric cars have 60-80%. Heating your house with gas has an efficiency of around 100%, heat pumps have 300%-500%.
